JOHN WALDHEIM, OF ELIZABETH, NEW JERSEY, ASSIGNOR TO UNDERWOOD TYPE-WRITER COMPANY, OF NEW YORK, N. Y., A CORPORATION OF. DELAWARE.

TYPEWRITING MACHINE.

Application filed April 9,

To aZZ whom it may concern:

Be it known that 1, JOHN WALDHEIM, a citizen of the United States,residing in Elizabeth, in the county of Union and State of New Jersey,have invented certain new and useful Improvements in TypewritingMachines, of which the following is a specification.

This invention relates to typewriting machines, and more particularly tothe kind used for continuous billing, shown in the patent to Vernery 8:Smith No. 1,132,055, of March 16, 1915, in which a folded pack ofwork-sheets or webs with interleaved carbon-sheets may be fed around aplaten to the printing point; the carbon-sheets being attached to acarrier to enable them to be shifted to untyped portions of theworkwebs.

The webs or continuous work-sheets usually have printed forms'thereonand may be drawn forwardly, after they have been typed, to a gage, priorto severing the typed forms from. the pack of continuous sheets.

The printed forms on the various sheets may include instructionsdiffering from each other, according to the several uses for which thecopies may be required. *For example, the original or outer sheet may besent to the customer. while the various copies may be intended fordifferent'departments. It is therefore desirable to be able to readilydistinguish the various copies to facilitate their sending to thevarious places for which they are intended. To do this, it has beenproposed to print the ruled forms and their respective instructions onthe various continuous work-sheets in different colors. It has also beenproposed to use work-sheets in which the materials are of differentcolors, in which case the forms may be printed thereon with the samecolored ink. This last-mentioned method, however, necessitates themaking of different worksheets separately, due to the differentlycolcred materials.

The object of the present invention is the provision of means toaccomplish the desired result without necessitating the printing of. theforms with different kinds of ink, or the making of the work-sheets ofdifferently colored materials.

For this purpose. I arrange to .provide the various forms with marks ofidentifica- 1920. Serial No; 372,445.

brought to the printing'point when the carbon-sheets are retracted,prior to the writing of a new set of forms, so that the first entrytyped on each set of forms, which may be an order number, may appear indifferent colors on the various forms.

In typing the body of the forms, it is sometimes desired to make certainentries other than the first entry stand out from the others which aretyped in black. For this purpose, such entries may be typed on the outersheet through-the red field of the usual bichrome ribbon. To have thisentry appear differently on the various carbon copies, the

carbons may be shifted relatively to the work-sheets, prior to makingthe entries, to bring the narrow fields of different colors to theprinting point.

'In some cases, where instead of having such entries appear in differentcolors, it is desired to have them appear in red as on the original,each carbon-sheet may be provided with another narrow field which may bered in color and adjacent to the other narrow field, all of the redfields being collectively shiftable to the printing point at will.

In the continuous billing machine, it is also desirable, at times, totype on the outer work-sheet, which is done through the usual ribbon,without reproducing the typewritten matter on the carbon copies. I

For this purpose, provision is made to permit the carbon-carrier to beretracted to an abnormal position to bring the leading edges of thecarbon-sheets below the printing point, thereby rendering themineffective for copying purposes.

To permit the carbons to be retracted to bring the narrow fields to theprinting point, or to permit the carbon-sheets to be renderedineffective, there may be provided a plurality of settable stops toco-operate with a relatively fixed stop to arrest the carbon-carrier indifferent positions when retracting the carbon-sheets.

The invention further relates to means to facilitate the assembling ofthe carbonsheets on the various holders of the carboncarrier, so thatthe difi'er'ently colored fields of the various carbon-sheets -mayregister with each other.

The invention may also be used to increase the use of the carbon-sheetssince the carbon-carrier may be arrested in different positions, thusenabling the spaces between the typg positions on the carbon-sheets tobe use Other features and advantages will hereinafter appear.

Figure 10 is a perspective view as seen from the back of a portion ofthe carboncarrier with the settable stop-member and the relatively fixedstop.

Continuous work-sheets 15, which may be folded to form a pack 16, asshown in Figure 6, and shown as separate sheets, for clearness, inFigures 1 and 7, may be inserted in the machine. The work-sheets may beled from any suitable source of supply over a rear rail 17 of anauxiliary carriage frame 18, comprising two end bars or rails 20 and 21,connected to travel with a platen-carriage 22.

The work-sheets 15v may be extended forwardly over acarbon-sheet-carrier.or carriage 23, supported on the end rails 20 and21. Carbon-sheets 24 are interleaved between the work-sheets 15, andextend forwardly from the carbon-sheet holders 25 on the carbon-carrier;The work-sheets and the carbon-sheets pass over a. shaft 26,'supportedon the platen-carriage, and extend downwardly around a platen 27 andbetween feed-rolls 28. At the front of the platen, the work-sheets andthe carbon-sheets are guided upwardly past the printing point, so thatthey may be typed upon by the typebars 29, the outer work-sheetreceiving its impressions through an inking ribbon 30, which may have ablack field 30 and a red held 30*, while the inner work-sheets receivetheir impressions through the interleaved carbon-sheets 2 1. The platenis mounted on a platen-shaft 31, rotatably mounted, so that theworksheets may be linespaced, in a frame 32, which may be swung aboutthe axis of a rod 33, supported in suitable brackets 34011 theplaten-carriage, for a purpose hereinafter described.

To line-space the platen after each line is typed on the work-sheet,there may be provided the usual line-space lever 35, which swings, whenoperated, about a pivot 36, to cause a toe 37 thereon to push aline-space slide 38 rearwardly. The line-space slide is provided wit-hapawl 40 to engage the teeth. 41 of a ratchet-wheel 42 to rotate a shaft13, supported in the carriage 22. The shaft 4-3 has secured thereto, atvits inner end, a gearwheel 44L, meshing with a pinion 15, revolu blysupported on the rod 33; said pinion being broad enough to engage with agearwheel 46, adjacent to the gear-wheel 44. The gear-wheel 46, however,is secured to the platen-shaft 31, which is normally in alignment withthe line-space shaft 43. Thus, as the gear-wheel 4-1 is rotated, theline-space movements are transmitted through the pinion 15 and the gearwheel 4:6 to the platen to feed the worksheets forwardly.

ne work-sheets 15'l1l2tjf be furnished with printed forms thereon, whichare of equal length. and extend lengthwise of said sheets. After theentries are made on each set of forms, the set may be'severed by a knife47' (Figure 7), supported in the swing-frame32, and extending lengthwiseof the platen'27. Since the printed forms are of successive equallengths, and the number of entries may vary on the different sets offorms, it is necessary to first gage the forms prior to severing. It isalso desirable to retract the carbon-sheets 21 to bring them to the nextsucceeding set of forms, and their leading edges below the cutting edgeof the knife before severing.

-To facilitate the shifting of the carbonsheets relatively to: thework-sheets, thev platen may be displaced by the swingframe 32, which islocked in printing position (Figure 7), by hooks 48 and 50 on the shaft26, which is spring-operated to hold the hooks 48 and 50 over studs 51on the swing-frame.

To release the swing-frame the hook 50 is provided with a finger-piece52, which may be pushed rearwardl to move the hooks 48 and 50 out ofholc in relation with the studs 51 on the swingrame. The typist thengrasps a front paper-table 53, forming part of the swing-frame, to swingsaid frame about the axis of the rod 33, to raise 7 lower the platen totyping position, While the work-sheets are held against the gage- -barwith their leading edges against the gage 54. After the frame has beenswung back, the set of typed or finished forms may be severed from thepack, by pulling them crosswise of the knife 47.

Provision is made to make distinguishing marks on the ,varioustypewritten forms after the sheets have been inserted in the machine.This may be done on each set of riage), may be provided each with acomparatively narrow field or coated surface 60, differing in color fromthe color of the coating which may cover the balance of thecarbon-sheets to form wide fields 61, which may be black in color. Thenarrow fields 6O, differing in color from each other, may be brought tothe printing point whenthe carbons are retracted or shifted relativelyto the worksheets. For this purpose, the stop-member 57 is provided,which may be pivoted to a bracket 62 on the carbon-carrier 23, so that aco-operative stop 63 thereon may be set into range of the stopv 58 toengage, on the return'stroke of the carbon-carrier, with the relativelyfixed stop 58, thus bringing the differently colored fields 60 to theprinting point (Figure 4), or, in other words, rendering them effective.The first entry may then be typed and copied on the inner sheets indifferent colors through the narrow fields 60 of the carbons, thedifferent colors serving as distinguishing marks for the variousWorksheets. The entry on the outer work-sheet may be. made through theblack field of bichrome ribbon 30. The line-space handle is nextoperated to feed the work-sheets and the carbons forwardly, thusbringing the black fields 61 of the various carbons into use for thebalance of the entries to be made.

' It should be understood that the fields of different colors may berendered effective at. any time. For example, if it is desired to makean entry appear in different colors after several entries havebeentyped, the platen may be lifted to permit the carbons to be shifted tobring the narrow fields to the printing point, but, instead of pullingthe work-sheets to the gage 54, they may be held tightly against thetable 53, or gage-bar 55, while the carbon-sheets are shifted by pushingthe carbon-carrier 23 rearwardly, the stop 63 having previously been setinto effective relation with the fixed stop. The platen is then swungdown, when the entries to appear in different colors on the variouswork-sheets may be made, after which the succeeding entries appear inthe same color as the preceding. entries.

As previously stated, the body of each carbon-sheet may be black, sothat the greater part of the typewritten matter may appear in black onthe various forms. It should be understood,however, that the differentlycolored fields may extend over the greater part or the whole surface ofthe carbon-sheets.

The carbon-sheets 24 may be held on their respective holders 25, byclips 64, pivotally supported on the holders. It will be seen by aninspection of Figure 1 that the carbon-sheet holders 25 are placed sideby side and successively further away from the platen. It is desirable,however, to assemble the carbon-sheets on the holders so that the fields60 on the various carbonsheets may register with each other. For thispurpose, each carbon-sheet may be provided at its edges with markings59, so that the corresponding markings on the opposite sides of thecarbon-sheets may be used to position the latter on the holders bybringing the markings in line with the back edges of the holders. Themarkings are spaced apart from each other distances equal to thedistance between the back edges of the successive holders, so that anycarbon-sheets may be secured to any one of the holders, the set ofmarkings used to position the carbon-sheet depending on the position theholder is to occupy on the carbon-sheet-carrier when attached thereto.

Sometimes it is desirable to type a set of forms without distinguishing:marks.

To'do this, the stop-member 57 may be set to a different position tobring a stop 65 thereon into effective relation with the fixed stop 58,so that the carbon-carrier may be arrested earlier during acarbon-sheet-retracting operation, so that the leading edges of theblack fields 6 1 are brought to the printing point; the differentlycolored fields thus falling short of being brought into use, as shown inFigure The set of forms may now be typed to have the typewritten matterappear on the various copies in the same color.

It is also desired at times to typewrite matter on the outer work-sheetwhich is not to appear on the carbon copies. For this purpose, provisionis herein made to shift the carbon-sheets 24 during thecarbon-retracting operation to bring their leading edges below theprinting point, thus rendering them ineffective, as shown in Fig ure Todo this, the settable stop-member 57 is provided with a stop 66, whichmay be set into efi'ective relation with the relatively fixed stop 58,to permit the carbon marriage to be moved rearwardly a greater extent toan abnormal position, to bring the leading edges of the carbon-sheetsout of range of the printing type-bars 29. The operator may proceed totype the entry which may be made on the outersheet through the ribbon30, without transferring the type impressions to the inner worksheets.

It should be understood that the differently coloredfields 60 of thecarbon-sheets may be made wider, so that they may remain in use forseveral line-space movements of the platen. The leading edges of thecarbon-sheets may also be drawn a greater distance below the printingpoint,

so as to allow several lines to be typed on .the outer sheet before thecarbons are brought into use. This may be done by having the stops 65,63 and 66 spaced further apart from each other to increase the extent ofthe rearward movement of the carbon-carrier.

To facilitate the setting of the stop member 57, so that thecarbonesheet-carrier may be arrested to render the black fields 61, orthe differently colored fields 60 of the carbon-sheets effective, orbring the carbonsheets to a non-copy or inefliective position,indicating means may be provided. The indicating means may comprise anindex plate 62 forming the upper part of the bracket 62, and having themarks B D and N, respectively, for the blacli color, distinguishingcolors and non-effective positions of the carbon-sheets; the stopmember57 being settable by means of a handle 67 and an indicator 6-8, whichmay point to B, D or N To hold the settable stop-member 57 in any one ofits positions, it may be slightly resilient and other.

provided with a projection 70, to snap into any one of aplurality ofholes 71 in the supporting bracket 62.

To enable copying on the various worksheets in red or in various colorsat the same time, the carbonsheets may each be provided with two narrowfields and 72, as shown in Figure 6, thus forming sets on the variouscarbon-sheets, the set of fields 72 nearest the leading edges of thecarbons being-of the some color, which may be red, thus ditl'ering fromthe black fields 61 of the carbons and from the differently coloredfields 60. It will be seen that with appropriate markin s on the indexplate 62*, the stop-member 5 may be set, so that the carbon-sheets maybe selectively positioned so as to bring the various sets of fields 61,60 or 72 to the printing point.

A further use of the invention may be to increase the period ofusefulness of the car-.

surfaces, have become worn. by the typebars 29, the'carbon-carriage 23may be permitted to move back a little further, as in Figure 8, and bearrested by the stop 74, thus permitting the unused portions between theused portions of the carbon-sheets to be brought into use, the unusedportions being brought successively to the printing point byline-spacingthe platen 27.

It will be seen that the stop 58 is not merely a stop but that it alsoserves as a master gaging device, and. that since it determines adefinite location for the carbons while the gage 54L determines adefinite position for the work-webs, the two gages 54: and 58 co-operateto locate the work-webs and carbons definitely with relation to each Thestepped stop device serves as an auxiliary gage to vary, by mechanicallypredetermined amounts, the position of the carbons relatively to themaster gaging device 58, such variations corresponding to the widths ofthe narrow color fields.

-Variations may be resorted to within the scope of the invention, andportions of the improvements may be used without others.
